sir logbook,

ganito po yung pagka-intindi ko diyan sa SQ and SPL. if you go to a disco house and listen to the sound, that is SPL. the focus of the sound is more on the bass. if you go to a jazz concert, that is SQ. you can hear the clarity of the music, and differentiate the sound produced by each instrument. of course balance lahat ng tunog dito.

some people like systems that has both SQ and SPL... some people calls it SQL.

actually, may nagsabi rin sa akin na okay na yung 2-way. i suggest that you try to listen to different setup, before you decide your own. just make sure na narinig mo muna yung bibilhin mong gamit. lagi kasi nasa huli ang pagsisi.
